looking at those 357 rounds on the 223 brass has me thinking a 23mm version in 9mm would be pretty slick on a tokarev m57. i cant seem to find a 9mm barrel to rechamber any were for one however. hell I could do a 9x25 on the thing .

was considering making one but im not sure about the barrel material or hardenss on a pistil with the lugs in the barrel an having the lug for the link would require a really big OD blank to staret with. i f I make one its going to be extra long. Like 6inches long with a extended bushing an built in compenstater etc.

i nned to look at what the 45 auto guys to to make barrels an go from there.

that Galil mag will need a bunch of tweeks an will need to be shimed to fire single stack

a 35 remington or any oterh longer build is not that much harder. just opent he mag well up move the trigger guard back, deal with the cross meamber hitting an weld some taps off a ak mag onto what ever mag firts your rund the best. not any harder than getting a 357 mag not feed an load.

NOT PLUG AN PLAY BUY NOT THAT HARD. TAKE A GOOD LOOK AT A SAGIA RECIVER AN COPY IT. USE SAIGA 308 MAGS IF YOU NEED TO PRICY BUT NOT REDICULAS.. YOUR NOT GOING TO NEED A DOZEN MAGS FOR ANY OF THESE HIGHER POWER RIFLES FOR ANY REAL WORLD REASON. A FAL MAG IS A GOOD CANIDATE AS IS M14. I can mage a g3 fit with some work an thre dirt cheap.

good point, but I do have a .223 fal boldt head in hand and a -74 kit so it could go eather way on a 357max with ak mags. with a 35 rem I would need to deal with the mag issue only as a 35 rem will fit right in a standard -47 boldt head, hummm dont know yet, I need to to do a 922 count and add that to the cost of build. muttman

if your going to reload an want to make it easy id go with the 357AR set up.

uses a 223 or even a 5,45 bolt lileky as is an you could solder in a ring into a x39 bolt as well on a blow back. you would have to load it a lot less hotter than if you were doing a 357 mag however.

If it were me (an I might build a 357max) id just go with a bulgy kit an add the 357 barrel
an then run likey pretty stock 223 mags. might have to tweek then a bit were the follower stop is. Id do it in a gas gun an it would be pretty much a simple barrel swap only with slight mag tweaks. the cost of used 223 brass is whats attractive for this build. IM betting the gun would shoot cast lead really well also at lower pressures id plan on a adjustable gas port.

In a blow back you going to have to watch pressure with much over a x39 type pressure. a 357 ar blow back would work but its going to have to be loaded really light an then look out if you ever get at a double charge easy to do in a big case like that.

I see a 357 mag ok in blow back, But the 357ar is so much better at every thing from the looks an can be loaded to at least 50,000 PSI.

You might be abkle to get him to ream the chamber cheap also avoiding buying a reamer or a already chamberbed barrel. .

that straght round could damm near be bored on a lathe an then just have the neck an throat cut with a sperate cheaper reamer. liikely could cut the sligh taper with just the travel on the tool post. its only going to be 1.5" or so.

you have a lathe correct???

If it were me an I was committed to a blow back in 35 or 9mm. I would build a 9mmx23win . I would make the chamber so i could use cut down brass an Id make the round also work in a tokarev pistol with a 9mm barrel. you would have the option of starline or win brass. the win brass will handel lots of pressure unsupported an is tough as hell. the 9x23 has 357mag power or better an will work in a 7.62x25 mag. there are 7.62x25 drums an high cap mags that may work like from a ppsh or others. this is a great idea for a blow back or gas an the mags alreadyexist as is. there is even mag well addapters out there to take them.

bg,
a lathe out back, no but I do have one at work and a bud that runs his mach. shop. so yes. I agree .223 brass is the way to go for this one. as it stands now the -74 kit is a 357 max and the l1a1 lower is for the .223 build. now I just need to get the time to work on them. muttman

Could use a 30 carbine magazine for 357 magnum rimless.
The 30 carbine magazines have been used for 7.62x25 with longer bullets.

TRUE I LOOKED AT THEM FOR A X25 AK BUILD.

YEA I AGREE AN IF YOU GOING TO GO WITH 223 BRASS MIGHT AS WELL MAKE THEM AS LONG AS POSSABLE AN GET SOME POWER. A GAS GUN IS A LOT EAISER TO MAKE AS ALL THE PARTS ARE IN THE KIT.

I HAVE BEEN LOOKING THIS OVER AN AN WONDERING HOW .32 CAL BULLET WOULD BE ON A SET UP LIKE THIS ??????? IT WOULD GIVE YOU A SHOULDER TO HEAD SPACE ON. MIGHT NOT BE ANY BETTER THAN A 300 BLACK OUT WITH A LOT MORE TROUBLE FOR NOTHING.

IM ASSUMING THE 357AR HEAD SPACES ON THE CASE MOUTH?????? ALSO ARE THERE FACTORY DIES FOR THE 357AR I FORGET ???

WITH ONCE FIRED 223 BRASS BEING REASONABLY CHEAP IT ONLY MAKES SENCE TO USE IT FOR A PROJECT LIKE THIS. MAKE SOME TRIM DIES FROM THE CHAMBER REAMER AN SET UP A LITTEL CUTTTING STATION AN YOU COULD COULD A LOT OF BRASS IN A HURRY

IF I COULD EVER FIND A 9MM TOKAREV BARREL iD BE ALL OVER DOING A 9X23 OR 24 0R 25MM

I have been tempted to just buy a 1911 in 38 super an chamber it to somthing like this. to much money. I have three m57 yugos an it would be nice to just find a 9mm an ream it.

1Biggun, With the longer .357" and .358" bullets that I was wanting to shoot, about as long of a case as I could go with was 1.595" -1.605" of the 357max... So thats what I did. The case does headspace on the case mouth, and you can use standard 357max dies (I'm using a Lee 38/357mag/357max die set with a replacement top punch for the pointed bullets). I plan on making a set of custom dies for it at some point as the Lee carbide dies I have been using remove the fireformed .005" case taper at each reload. There doesn't seem to be an issue with overworking the brass as I've reloaded some cases 12x, but it might be nice if it kept the extra capacity.
There is a .32 or .33 ar15 round. I've got a pic of it based on a 357max case showing the difference in it and a 223 in the webbing.

SO THE 357 MAX IS A FACTRY MADE BRASS ROUND??? IS THE 357 MAK PISTOL PRIMER ?? I SEE THE POCET IS MUCH DEEPER. 223 THICKER IN THE BASE.

I REALLY NEED TO LOOK INTO ONE OF THESE. GOOD TO KNOW 357 DIES MIGHT WORK AT LEAST THE LEES.

WHAT REAMER DO YOU USE AN DO YOU OWN IT?????

IS THAT 357 MAX ROUND NECK TURNED OR NECK REAMED?? I SEE WHAT LOOKS LIKE A SMALL SHOULDER. OR IS THAT FROM FORMING IT OR FROM FIRING IT???

I REALLY WANT TO DO A CUSTOM TOKEREV T33 OR M57 WITH A CUSTOM LONG BARREL IN A 9MM MAGNUM TYPE ROUND. WAS THINKING OF HUNTING WITH IT. IF A 357 IS USED THEN THERE IS NO REASON A 357 MAX OR 9X23 OR SIMULAR WONT.

IF i CAN USE THE 1500 ROUNDS OF FIRED A LOT BRASS OUT OF MY VSARMIT RIFLE AS DISPOSABLE CSSES THEN ALL THE BETTER.

1Biggun, the pic above is a wildcat with .338 bullets that was brought up in my 357AR build/design thread on weapons guild. The 357 max uses small rifle primers as does my 357AR. I had hoped on going with 357 Maximum brass (which only remington makes every so often) The 357 Max cases only need the rim turned off to work, until you factor in the case web. I didn't know if it was a toss up with the thicker case head and thinner web, v/s the 223, but I figured the 223 case was built for much higher pressures than a 357 max case was....So thats what I went with. I have a bunch of 357 max cases, but I'll just use them for a single shot build or something. The 357AR is really just a 357 Maximum that is rimless and loaded to higher pressure. Since it's a semi there is a few thousands more body taper in the chamber, but thats about it.
I made one 357AR reamer for .347"/.357" barrels and another one for .350"/.358" barrels. I also had a reamer made with a floating pilot, and pilots for both barrels. Most of the 9mm and 38/357 barrel blanks have the same land and goove diameters and are sort of generic barrels with different twist rates.
I turned the necks on the formed cases as the case shoulders vary in thickness and depending on the case forming process you can end up with different neck thicknesses. I'm thinking about changing over to reaming as I believe it might be faster.
I had hoped to take it deer hunting this year, but it's not looking like I'll get to go this year.
